BN-220 3.0 V-5.0 V Level TTL, GNSS Module, M8030, NEO-M8N GPS GLONASS Dual Module GPS Antenna, Built

Getting started with the BN-220 3.0 V-5.0 V level TTL, GNSS module, M8030, NEO-M8N GPS GLONASS dual module GPS antenna, built-in flash 

We’re going to look at how GPS can show us longitude and latitude coordinate of our current locations.

 Hardware required

• Arduino UNO
• GPS NEO-M8N GPS GLONASS

 Connecting the Hardware

• 1 GND (Black)-> GND
• 2 Rx (White) -> D4 (of Arduino)
• 3 Tx (Green) -> D3 (of Arduino)
• 4 VCC (Red)-> 5v or 3.3V

Installing a library: TinyGPSplus

Before uploading the sample sketch you need to have the TinyGPSplus  library. This can be found in Manage Libraries. You can visit here to see how you can add your library.

Upload the sample sketch

You can go in examples and find FullExample to sketch. Change line 9 like this:

static const uint32_t GPSBaud = 9600;

Upload the codes and change the baud rate of the Serial monitor to 115200. The codes should look like this:

#include <TinyGPSPlus.h>
#include <SoftwareSerial.h>
/*
This sample code demonstrates the normal use of a TinyGPSPlus (TinyGPSPlus) object.
It requires the use of SoftwareSerial, and assumes that you have a
4800-baud serial GPS device hooked up on pins 4(rx) and 3(tx).
*/
static const int RXPin = 4, TXPin = 3;
static const uint32_t GPSBaud = 9600;

// The TinyGPSPlus object
TinyGPSPlus gps;

// The serial connection to the GPS device
SoftwareSerial ss(RXPin, TXPin);

Before uploading the program , Tx and Rx of arduino and GPS must be disconnected then Upload the program and open up the serial monitor from the Arduino IDE. You can now see the coordinates (Longitude ,Latitude) of the place you are.
